Thank you......this helped a lot!
what is the difference between coal and grahite
I think the time frame given for the ages of coal is incorrect, actually much of the information here is based off of long held assumptions that are now being questioned. It takes a long time before other ideas are given even the slightest consideration.
very informative and well presented.
How to Lignite carbon percentage 60-70 as well as moisture 75% ! and in sub-bituminous carbon content 35-45 %? Please, upload the right information. You don't know about coal.
Very clear and helpful! Thanks!
how does the plant material become pure carbon? what happened to everything else? why doesn't peat decompose and lose its carbon when it's mostly burned off as CO2 by the bacteria? where do the hydrocarbons in bituminous coal come from? where do they go when the coal turns to anthracite?
